We conclude that no single 'critical temperature' for thermal fracturing or heat treatment can be specified for any particular raw material, as has so often been attempted, because threshold temperatures exist in relationship to specimen sizes.
In benefit of human health, our immediate deliverable is a macro-exposure/micro-response relationship to characterize failure thresholds and safety limits of neurodegeneration across the scales.
Constant false alarm rate (CFAR) detectors are important because they eliminate the sensitivity of the probability of false alarm (Pfa) and threshold relationship to variations in the clutter power level [20, 21].
The fourth step in the utility threshold analysis is to translate the threshold pressure in any nonlinear attribute-pressure relationship to values of easily-measured indicators representative of the status or trend in the ecosystem attribute.
The difference is that for a PRE of smaller than some critical value (e.g., the threshold), ESF will not occur in the relationship of threshold but may still occur at a lower probability in the relationship of probability.
Donations to Threshold, P.O.
The potential existence of (i) non-linearities in the relationship and (ii) threshold effects of the impact of the DES per caput on growth which depend upon the initial level of GDP per caput are established.
In order to quantify the relationship between threshold and slope, we calculated the correlation for threshold versus slope across all data points, irrespective of subject or stimulus type.
Early in this dynamic relationship, the threshold for cellular damage is shifted such that neuronal loss and decreased protein metabolism may in fact precede changes related to critical CBF, particularly in peri-infarct areas [ 2].
Although there was no main effect of slope, we did find a moderate but significant correlation between detection threshold and slope for our human subjects (Spearman's rank correlation, ρ = −0.45, p =.0007), in line with the relationship between threshold and incremental sensitivity seen in ferrets.
